Abstract (en)
[origin: EP2587876A1] A feedback method and apparatus are provided for Cooperative Multi-Point (CoMP) communication in a communication system. The method includes checking a number of feedback allocations configured by Radio Resource Control (RRC) signaling, determining a number of bits of an aperiodic feedback indicator based on the checked number of feedback allocations, receiving Downlink Control Information (DCI) including the aperiodic feedback indicator, interpreting the aperiodic feedback indicator, based on the determined number of bits of the aperiodic feedback indicator, and performing aperiodic feedback of at least one feedback allocation, based on the aperiodic feedback indicator.
